CARPET-STRETCH ER.

SPECIFICATION forming part of Letters Patent No. 242,960, dated June 14, 1881,

Application filed April 521, 1881. (No model.)

To all whom it may concern:

Be it known that I, DANIEL NEFF, a citizen of the United States, residing at Amsterdam, Montgomery county, and State ot' New York, have invented a new and useful Improvement in Extension Self-Adjustin g Carpet-Stretchers, of which the following is a specification.

My invention relates to improvements in carpet stretchers. I attain the object by a mechanism illustrated inthe accompanying drawings, in which- -Figure l is a side elevation of the machine complete. Fig. 2 is a plan of the cross-bar head to rod E of Fig. l. Fig. 3 is a plan of the crossbar head ofrod A, showing the pinsel.

Similar letters refer to similar parts throughout the several views.

My invention is constructed as follows. viz:

I have two rods, A and E, Fig. 1, of anyY suitable size andlen gth,substantially as shown. On one end of rod A, Fig. l, I tix a cross-bar head of sufcient dimensions to lcorrespond with the proportions of the complete machine, and into lhe under surface and near the outer ed ge of the cross-bar head I), on forward end of rod A, are inserted metal pins or teeth, as shown in Fig. 3 by d d d d, the olce of which teeth or pins is to pierce and hold in a fixed position a carpet when it is stretched. 'Ihe other rod, E, is made of the same general size as rod A, at the outer end of which there is a cross-bar head, h, the office of which is that ot' a rest to crowd against the wall ou the opposite side of theroom from the crossbar head I). The other end of rod E has an open mortise, through the sides of which I have holes pierced to receive a pin. Said open mortise is made to receive the upright lever F, hereinafter referred to. These rods A and E are arranged to move back and forth-E over A-' by means of an uprightlevcr, F, the lower end of which lever has an open mortise to allow bolt, z', passing through it and theholes made in the sides ofthe open mortise ofthe rod E, which pin serves as a center around which the rod E and lever F oscillate freely. There are two straps, Gr G', in form of loops, the ends of which are fastened to the respective sides of rod E, as shown, and from thence pass downward, looping around and through which rod A freely passes as its position is changed backward or forward by the movement of lever F when in practical use.

On the upper side of rod E, I place a staple, N, to hold a retaining wire loop, H, as shown, the opposite end of which retaining wire loop passes around the upright lever F, (above rod E,) and so arranged as to allow the retaining wire loop to move up and down lever F and to rest in notches m formed in the front or t'orward side ofthe upright lever F, the office of which retaining wire loop and notches is to hold the upright lever F in a fixed position after the carpet is stretched to the. required place, and to retain the strain of the stretcher when in practical use.

An extension selfadjustable carpet-stretcher, constructed ot' rods Aand E, lever F, loops G G', retaining wire loop H, head and foot cross-bar heads h and D, andthe pins or teeth el, arranged substantially as described and set forth.

DANIEL NEFF.
